The device comes without a manual or instructions. I can't figure out how to adjust the volume on the device when I start the car for the first time. The volume of the radio is too loud even on level 1. The volume of the radio is much higher than other media. You hear when you turn on the radio or start the car. I can't figure out how to set up my own radio settings. It searches and scans, but only remembers the available channels. Bluetooth settings are erased randomly. The devices have to be reprogrammed every week. Icons on the home screen cannot be rearranged. The instruction icon contains very bad instructions. Bad English. The device does not live up to what the instructions say. The device has only one set of RCA connectors. Will not work with a 4 channel amp. The power cord of the amplifier works in reverse. Turns off the amplifier when the power is turned on. The auxiliary input is a short cable on the back of the device. There is no memory card slot. Where to stop! Too many bugs in this device.
